PAPER-BOX-TOPPING MACHINE.

Specification of Letters Patent.

Patented Dec. '7., 1915.

Application led November 4, 1912. Serial No. 729,427.

To all whom t may concern Be it known that I, EDWIN G. STAUDE, a citizen of the United States, and resident of Minneapolis, in the county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Paper- BoX-Topping Machines, of which the following is a specification.

The object of my invention is to improve the machine shown and described in -m pending application, Serial No. 711,001,1led July 22, 1912. In this machine I have found it difficult to gum the label and then place it smoothly and evenly on the top of the boX cover. The label is usually made of thin paper and I have found it had a tendency to wrinkle, particularly after it had been moistened by the application of the glue thereto.

My present invention 'contemplates the elimination of this Adifficulty and objection by the application of the glue to the cover itself and then applying the dry label to the glued surface of the cover.

The inventionpconsists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is'a plan view of a paper boX topping machine em.

bodying my invention, Fig. 2 is a longitudinal, vertical, sectional view of the same, Fig. 3 is a transverse sectional view taken on the line 'u1-fw of Fig. 2, Fig. 4 is a detail sectionalview, showing the mechanism for applying the glue to the surface of the cover, Fig. 5 is a detail sectional View, showing themeans for gripping the label and pressing it on the surface of the cover, Fig. 6 is a similar view, showing the mechanism in the act of applying the label to the cover, the gripping means being released, Fig. 7 is a detail sectional view on the line y-y of Fig.- 8, Fig. 8 is a sectional view on the line -w of Fig. 7.

'In the drawing, 2 represents a suitable frame, in which the operating mechanism of the machine is mounted. The side rails of the frame on one side of the machine are provided with inwardly projecting lugs 3 and 4, preferably integral with the frame and having bearings for upright screw shafts 5. (See Figs. 2 and 3.) On these screw shafts yokes 6 are mounted and arranged to project into the space between the side rails of the frame, as 4shown in Fig. 3, and provided with bearings for parallel transverse shafts 7. At the upper ends of the screws 5 I provide beveled pinions 9 meshing with similar pinions 10 on a horizontal shaft 11 having an operating wheel 12 at one end of the machine. By revolving this sha-ft 11 the screw shafts 5, (of which I prefer to provide three in this machine) will be operated simultaneously to raise or lower the yokes 6 and the transverse shafts 7. The yokes Vare connected with one another, preferably by horizontal parallel rods 13 and 14, and these rods are connected with one another by transverse Ishafts 15. vBrackets 16 and 17 have clamps 18 slidable on said shafts and locked thereon by means of screw wheels-19, and upon these brackets angle bars 20 are supported in parallel relation with one another to form guide-ways for the-moving box covers. These brackets 16 and 17 maybe adjusted toward or from one another transversely of the machine to adapt the guide-ways for different widths of box covers.

At one end of the machine a hopper 21 isV provided, in which the box covers are placed, one upon another, with depending flanges. The hopper is open at the bottom, as indicated in Figs. 2 and 3, and a sprocket belt 22, having pins 23 thereon, is mounted t0 operate beneath the hopper, the pins successively engaging the forward flange of the lower cover and drawing it out from beneath the pile of covers. The sprocket belt operates over sprocket wheels 24 mount ed on the'shafts 7, the middle portion of the belt being held against the cover by a guide 26 mounted in brackets 27 -which are also adjustable on the shafts 15 transversely of the machine. rIhe boxes are held down on the guide-ways 'by suitable means, such as bars 28 having pins 29 which are vertically adjustable in clamps 30 adjustably lso mountedon a transverse shaft 31. In the operation of the machine, the covers will be fed, one at a time, from the hopper by the movement of the sprocket belt.

Mounted in bearings near the -middle portion of the machine is a shaft 32 on which a cylinder 33 is secured. This cylinder has a series of longitudinal dovetailed slots 34 arranged at intervals in its periphery. A curved plate 35 is adapted to fit the surface of the cylinder and is provided with a series of bolts 36 to slip into the slots in the surface of the cylinder. The heads of these bolts are counter-sunk in the plate 35 and when tightened will lock the curved plate firmly to the surface of the cylinder. Beneath the shaft 32 is a shaft 37 on which a series of segmental sections 38 are keyed, said seri-ionsV having projecting points or toes 39 which are adapted to engage the forward flange of the boX cover and feed it beneath the cylinder 33. A second series'of segmental sections 40 is provided, having curved slots 41 in their hubs to allow for rotary adjustmentof these sections on the shaft 37, the adjustment being limited by the engagement of the shaft key with the ends of the slots. The hubs of these sections are also provided with teeth 42 adapted to mesh with a pinion43 mounted on a shaft 44 having a squared outer end 44a (see Figs. 7 and 8) to receive a- Wrench or other tool, for the purpose of rotating the sections 40 and changing the relative position of these sections and the section 38. v

A gluing roll 48 is mounted in bearings above the glue pot 49 and is adapted to contact with the surface of the plate 35 and also with a roll 50 which is mounted on the walls of the glue pot and partially immersedV in the glue therein. As the cylinder\33 revolves, the roll 48 will contact with the plate 35 and will be out of contact with the portion of the cylinder surface not covered by the plate 35. This plate can be readily removed for the insertion of another one in the cylinder to adapt the gluing mechanism for covers ofvdifferent length or width. A scraper plate 51 is preferably mounted on the glue pot, having an adjusting device 52.

Above the gluing mechanism I provide a label feeder, consisting of a hopper 53 and feed wheels 54vmounted in brackets 55. A roll 56 is provided below the feed wheels having belts 57 between which and the feed wheels the labelsl are fed. The feed belts extend downwardly and are supported by a comparatively small roll 58.

Near the discharge end of the feed belts I arrange shafts 59 and 60, one above another. On the upper shaft is a rolll .61 having a recess-62 in its spherical surface in which a rock shaft 63 is arranged, carrying a series of spring-pressed grippers 64.

A stationary cam 65 is loosely mounted on the shaft 59 andthe rock shaft 63 is provided with an arm 66 to ride on the face of the cam. Normally the grippers will lie within the recess in the roll 61, as indicated in Fig. 5, the arm 66 riding 'on 'the high part of the cam. As soon, however, as the arm reaches the low part of the cani the grippers will be forced outwardly by the spring 67 and will grip the label as it is fed down between the roll 61 and a comparatively small roll 68. Spring guards 69 are provided to hold the forward portion of the label on the roll 68 until the grippers, operating between the guards, have engaged the label.

Upon the shaft 60 I arrange a series of segmental sections and operating means therefor corresponding to those shown and described with reference to Fig. 4, and I will designate these sections by the same reference numerals with the addition of the eX- ponent a, and I will now describe certain means for locking the segments on the shaft and common to both the shaft 60 and the shaft 37, but illustrated in Fig. 8 in connection with only the shaft 60. It will be understood, however, that the Same mechanism is employed in the segmental roll beneath the gluing roll 33.

45a represents heads mounted on the shaft 60.

46a is an exteriorly threaded collar and 47 1 an interiorly threaded lock nut engaging the threads of said collar and by means of which the adjacent head 45a can be moved inwardly to clamp the segmental sections against the opposite stationary head 451. Between the segmental sections I prefer to provide collars 47 which are readily removable when the sections are released to allow for the proper adjustment and spacing of the sections to adapt them for box covers of different width. Whenever `it is desired to change the adjustment of the sections to adapt the feeding device for box covers of different length, the lock nut 47a is loosened and then by means of the pinion 43 the segments 40a can be adjusted to increase or decrease the peripheral bearing surface for the boX covers.

The movement of the roll 61Y and the sections 38a will be so timed that the forward end of the boX cover will register with the forward end 'of a label and just before the label contacts with the forward end of the cover the grippers will release the label and will be swung back to their normal position within the recess G2. The passage of the label and cover will then continue and as the label is laid upon the cover surface it will be pressed snugly against it by the peripheries of the'roll 61 and the sections 38 and 40L and when the cove'r has been dismean-fia charged it will drop upon an inclined plate 70 with .the label smoothly and evenly glued to the cover surface.

In the opera-tion of the machine, the' ond one comes along and pushes the foremost one into the gluing'mechanism. This movement will be continued through the machine, the succeeding covers feeding the foremost one to the gluing mechanism and i to the label applying roll. The lower shaft 60 has a driven pulley 71 thereon and drives the u per shaft 59 through gears 72. A shaft 3 is geared -to the shaft 60 and also to the shaft 37 of 'the gluingvroll, which in .turn is geared to the rolls 48 and 50. Theroll 56 is driven through a belt 74 from the shaft 60 and the feed belt 22 for the lbox covers is driven through a belt 75 from the shaft 37. I prefer .alsoto provide hand wheels 7 6 and 77 on the shafts 60 and 37 for convenience in adjusting the rolls in their proper relative position with respect to the segmental sections beneath, and thereby properly time the movement of these rolls v to the travel of the box covers and the labels.

Invarious ways .the details of construction may be modified and still be within the scope of my invention.
